Abstract
A practically untested method of final felling was evaluated theoretically with regard to conditions in southern Sweden. The fundamental idea is that small trees in a stand are treated in a different way to the large trees (diameter grading). Basically, this means that small trees are chipped without branching or bucking instead of being processed into industrial wood. The hypothesis is that the new method will provide a greater gross margin as well as improving the fuel production in the final felling. A change to the new method would, in a typical stand with numerous small trees, increase the yield of fuel per hectare from 75 to 105 m{sup 3} (magnitude, solid volume) if all trees under 16 cm at breast height were chipped. The gross margin is rather more difficult to assess. A change of method does not give any marked change - in the analysis - with current price relationship, under the condition that only pulp wood is transferred to fuelwood. Existing technology should make this method interesting in places where there is a high demand for fuelwood in relation to the competing assortment. Semi-practical experiments and certain developmental inputs are needed before this method can be established.
